What will happen in The Flash season five?

As the title of episode one suggests, the new season of The Flash will see the return of Nora Allen (played by Jessica Parker Kennedy), AKA XS, the future daughter of Barry Allen (Grant Gustin) and Iris West-Allen (Candice Patton).

She previously starred in the Arrowverse crossover story Crisis on Earth-X, and then reappeared during the season four finale to tell her parents she had made, “a big, big mistake.”

As well as revealing what this will be, The Flash season five will also introduce new supervillain Cicada (Chris Klein).

Cicada is the superhero name of David Hersch, who will be introduced in episode two of the series.
